The working principle is as follows: this stem cell import equipment, disinfect the lesion position through the iodophor before the use, disinfect the rubber disc 34 of placing 1 lower surfaces of dish simultaneously, put into sleeve pipe 6 with the syringe cylinder, and fixed lug 13 through the setting of 6 inner walls of sleeve pipe fixes the syringe, fixed lug 13 fixes sleeve pipe 6 under two 32 effects of spring, be a high transparent nontoxic material through sleeve pipe 6 with place dish 1 and make, be convenient for observe the syringe position through seeing through sleeve pipe 6 and placing dish 1, the manual syringe cylinder that promotes makes the syringe needle point pass holding ring 11.
The syringe needle is aligned to a lesion part, the driving gear 22 arranged on the outer side of the rotating disc 3 is manually rotated, the rotating disc 3 is convenient to rotate in the limiting groove 2 in a fixed-axis mode through the driving gear 22, the two sliding rods 5 can only move oppositely or back to back in the two vortex grooves through the sliding groove 16, the sliding column 801 penetrating through the through hole in the inner wall of the disc 1 is fixedly connected to one side of the pushing block 8, axial limiting is carried out through the sliding column 801 sliding in the through hole, and the two sliding rods 5 are enabled to always move oppositely or move back to back in the two symmetrical vortex grooves 4.
When the driving gear 22 is manually rotated, the driven gear 23 engaged with the driving gear 22 can be rotated, a threaded hole 25 is formed in the center of the driven gear 23, a screw 24 is screwed in the threaded hole 25, and the driving gear 22 can be rotated by overcoming the friction force generated by the screw 24 rotating in the threaded hole 25 by arranging the threaded hole 25 and the screw 24, so that the rotating disk 3 can not easily rotate and can be stably kept in a placed state.
When the driving gear 22 drives the two driven gears 23 to rotate reversely, the two screws 24 are provided with opposite thread structures, so that the two screws 24 move upwards in the threaded holes 25, the two screws 24 pull the piston block 26 at the bottom of the adsorption cavity 28 upwards to move upwards, a one-way valve is arranged at the communication part of the adsorption cavity 28 and the negative pressure adsorption port 27, when the piston block 26 moves upwards, air in the negative pressure adsorption port 27 is sucked out, so that negative pressure is formed in the negative pressure adsorption port 27, the rubber disc 34 at the negative pressure adsorption port 27 is tightly attached to the skin, the whole placing disc 1 is fixed, and the placing disc is matched with an injection device to be fixed.
The driving gear 22 is rotated clockwise, so that the slide bars 5 move horizontally in the volute-shaped grooves 4, when the two slide bars 5 move in opposite directions in the volute-shaped grooves 4, the two slide bars 5 move in opposite directions, the sliding columns 801 at the bottoms of the slide bars 5 move in opposite directions along with the slide bars 5, through the through grooves 701 formed in the upper surface of the pushing block 8 and used for limiting sliding of the slide bars 7, the pushing block 8 pushes the slide bars 7 to move downwards in the through grooves 701, the sleeve 6 moves downwards along with the slide bars 7, and the syringe in the sleeve 6 moves downwards integrally.
When the syringe needle moves down and pierces through the skin at lesion position, continue clockwise rotation along with driving gear 22, syringe needle position downstream in holding ring 11 and when piercing through the skin at lesion position to certain degree of depth, promote the flexible post 10 of 8 one sides of piece and pass through the opening of holding ring 11 both sides, and fix the syringe needle through flexible post 10, it is fixed to promote flexible post 10 to carry out the opposite direction centre gripping to syringe needle in holding ring 11 through setting up, can prevent effectively that the syringe needle from taking place the skew, make it aim at the lesion position all the time, guarantee that the injection position is accurate.
As the driving gear 22 continues to rotate, the two sliding rods 5 continue to move towards each other in the spiral groove 4, the pushing block 8 at the bottom of the two sliding rods 5 pushes the telescopic column 10 to continue to move relative to each other against the first spring 33, so that the telescopic column 10 is gradually accommodated in the first spring 10, the needle of the syringe is further fixed, so that the syringe remains in place in the sleeve 6 after moving downwards for a while, with the piston handle of the syringe at the bottom of the two push rods 19, the bottom of the pushing block 8 is fixed under the combined action of the telescopic column 10, the two sliding rods 5 move oppositely to push the pushing rod 20 in the limiting opening 18 to rotate in the vertical direction by taking the pin shaft as the center of a circle, the pushing rod 19 rotates along with the pushing rod 20, when the two pushing rods 19 are contacted with the piston handle, the two pushing rods 20 push the piston handle in a mutually staggered way, and the piston handle moves downwards stably to inject the stem cells to the lesion part.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
